Bug: "git log --format='format:%+s%+b'" doesn't insert newline before body

Hello.

Steps to reproduce: $ git init $ >123 $ git add 123 $ git commit -v -m 'This is subject' -m 'And this is body' $ git --no-pager log -1 --format='format:%+s%+b'

Actual results: ```

This is subject And this is body ```

Expected results: ```

This is subject

And this is body ```

$ git --version git version 2.9.2

Please fix.
